Accordingly, it is possible to adopt a structure in which the A axis and the B axis are inserted and tightened and fixed with nuts.
本発明により車椅子にあらかじめテーブルを取り付けておけば、テーブルを回転移動することで、乗降することができ、利便性が向上する。 If a table is previously attached to a wheelchair according to the present invention, it is possible to get on and off by rotating the table, and convenience is improved.
座幅が異なる車椅子であっても、２軸連結器が幅の調節機能を有しているため、既存の車椅子の寸法であれば、取付が可能である。 Even if the wheelchairs have different seat widths, the two-axis coupler has a function of adjusting the width.
２軸連結器の軸間の長さを任意に調整又は選択することで、テーブル面の高さを任意に調整又は選択することも可能である。 It is also possible to arbitrarily adjust or select the height of the table surface by arbitrarily adjusting or selecting the length between the axes of the two-axis coupler.
以下、図を用いて車椅子用テーブル（以降、テーブルと称する場合がある）を例示説明する。 Hereinafter, a wheelchair table (hereinafter sometimes referred to as a table) will be described with reference to the drawings.
テーブル本体１と取り付けガイド２及び３とを、２軸連結器４Ａ、４Ｂをもって連結させ、組み立てが完成した後に、車椅子肘掛部にテーブルを載せ、取り付けガイドを肘掛部に取り付け固定バンドで締め付け固定する。 The table body 1 and the mounting guides 2 and 3 are connected by the two-axis couplers 4A and 4B. After the assembly is completed, the table is placed on the wheelchair armrest, and the mounting guide is fixed to the armrest with a fixing band. .
テーブル本体１と取付ガイドとの組み立ては、テーブルを回転移動時の支点となる側に取付ガイド２を、移動する側に取付ガイド３を取り付け、支点となる側に２軸連結器４Ａを、移動する側に２軸連結器４Ｂを用い、テーブルに備えた軸受５と、取付ガイドに備えた軸受５に２軸連結器の軸６Ａ，６Ｂ、７Ａ、７Ｂ各々の軸を差込み、固定ナットにて仮止めをしておく。 The table body 1 and the mounting guide are assembled by mounting the mounting guide 2 on the side that becomes the fulcrum when the table is rotated, the mounting guide 3 on the side that moves, and the biaxial coupler 4A on the side that becomes the fulcrum. The biaxial coupling 4B is used on the side to be mounted, and the shafts 6A, 6B, 7A and 7B of the biaxial coupling are inserted into the bearing 5 provided on the table and the bearing 5 provided on the mounting guide, and fixed nuts are used. Make a temporary stop.
軸受５は、例えば矩形の立方体で構成され、中心部に孔を設け２軸連結器４Ａ、４Ｂの軸が貫通されるように構成されている。軸受のテーブル又は取付ガイドへの固定は、接着剤、ネジなどを利用することができる。 The bearing 5 is configured by, for example, a rectangular cube, and is configured such that a hole is provided in the center and the shafts of the biaxial couplers 4A and 4B are penetrated. For fixing the bearing to the table or the mounting guide, an adhesive, a screw or the like can be used.
軸受への２軸連結器の取付は、軸受の孔に２軸連結器の軸を通し、ナットで固定するものであるが、２軸連結器Ａには、手前のナット側調整軸６Ａに受けワッシャー１１を設け、奥側の一方には押さえワッシャー９を、もう一方の調整軸６Ｂにはスペースワッシャー１０が設けられている。押さえワッシャー９とスペースワッシャー１０は、調整軸６Ａ、６Ｂに回動不動に固定されており、ナット８を締め付けることで、受けワッシャー１１と押さえワッシャー９にて、もう一方の受けワッシャー１１とスペースワッシャー１０において、軸受を挟み込んで軸受に固定される。また、押さえワッシャー９には複数個所の突起部を設け、この突起部が軸受に入り込むことで、軸の回動を防止しテーブルの位置を安定的に維持することが可能となる。また、スペースワッシャー１０には、突起部を設けず軸との回動を可能にすることで、当該軸を支点としてテーブルの回転移動が可能となるよう構成している。 The biaxial coupler is attached to the bearing by passing the shaft of the biaxial coupler through the hole of the bearing and fixing with a nut. The biaxial coupler A is received by the nut-side adjustment shaft 6A in front. A washer 11 is provided, a pressure washer 9 is provided on one of the rear sides, and a space washer 10 is provided on the other adjustment shaft 6B. The holding washer 9 and the space washer 10 are fixed to the adjustment shafts 6A and 6B so as not to rotate. By tightening the nut 8, the receiving washer 11 and the holding washer 9 are used as the other receiving washer 11 and the space washer 10. , The bearing is sandwiched and fixed to the bearing. Further, the pressing washer 9 is provided with a plurality of protruding portions, and the protruding portions enter the bearing, thereby preventing the shaft from rotating and maintaining the position of the table stably. Further, the space washer 10 is configured so that the table can be rotated with the shaft as a fulcrum by allowing the space washer 10 to rotate with the shaft without providing a protrusion.
２軸連結器Ｂには、手前のナット側調整軸７Ａに受けワッシャー１１を設け、奥側には押さえワッシャー９を設け、もう一方の調整軸７Ｂにも同様に、手前のナット側軸に受けワッシャー１１を設け、奥側には押さえワッシャー９を設ける。押さえワッシャー９は、調整軸７Ａ，７Ｂに回動不動に固定されており、ナット８を締め付けることで、受けワッシャー１１と押さえワッシャー９にて、軸受を挟み込んで軸受に固定される。また、押さえワッシャー９には複数個所の突起部を設け、この突起部が軸受に入り込むことで、軸の回動を防止しテーブルの位置を安定的に維持することが可能となる。２軸連結器Ｂが設置される側は、回転移動時の移動側となるため、２軸共軸受に固定される構成としてる。 In the biaxial coupler B, a receiving washer 11 is provided on the front nut-side adjustment shaft 7A, a holding washer 9 is provided on the rear side, and the other adjustment shaft 7B is similarly received by the front nut-side shaft. A washer 11 is provided, and a pressure washer 9 is provided on the back side. The holding washer 9 is fixed to the adjustment shafts 7A and 7B so as not to rotate. When the nut 8 is tightened, the receiving washer 11 and the holding washer 9 sandwich the bearing and are fixed to the bearing. Further, the pressing washer 9 is provided with a plurality of protruding portions, and the protruding portions enter the bearing, thereby preventing the shaft from rotating and maintaining the position of the table stably. Since the side on which the biaxial coupler B is installed is the moving side at the time of rotational movement, it is configured to be fixed to the biaxial co-bearing.
テーブル１を車椅子に取り付けるには、取付ガイドの仮止めが完了したテーブルを椅子の肘掛にのせ、左右の取付ガイドが肘掛部の真上になるように、テーブルを回転移動の支点となる側の取付ガイド２と車椅子肘掛部を固定バンドにより固定する。その後に移動する側の取付ガイド３を、車椅子肘掛部の真上になるよう、取付ガイドを左右に移動調整し、移動する側の取付ガイド３と車椅子肘掛部を固定バンドで固定する。 To attach the table 1 to the wheelchair, place the table on which the mounting guide has been temporarily mounted on the armrest of the chair, and place the table on the side that will serve as the fulcrum for rotational movement so that the left and right mounting guides are directly above the armrest. The mounting guide 2 and the wheelchair armrest are fixed by a fixing band. Thereafter, the mounting guide 3 is moved and adjusted right and left so that the mounting guide 3 on the moving side is directly above the wheelchair armrest, and the mounting guide 3 on the moving side and the wheelchair armrest are fixed with a fixing band.
車椅子に固定されたテーブル１は、２軸連結器が仮止めの状態であるため、テーブルが椅子の中央になるようテーブルを左右に移動調整後、ナット８を締め付けて固定する。 Since the table 1 fixed to the wheelchair is in a state in which the two-axis coupler is temporarily fixed, the table 8 is moved and adjusted left and right so that the table is in the center of the chair, and then the nut 8 is tightened and fixed.
車椅子にテーブル１の取り付けが完了すると、車椅子への乗降がテーブル１により閉ざされるため、取付ガイド３の固定バンドを外し、テーブル１を回転移動して車椅子座面を開放する。次に車椅子に座りテーブル１を回転移動して戻し、固定バンドにて肘掛部に取付ガイドを固定する。 When the mounting of the table 1 on the wheelchair is completed, the boarding / alighting on the wheelchair is closed by the table 1, so the fixing band of the mounting guide 3 is removed and the table 1 is rotated to open the wheelchair seating surface. Next, sitting on the wheelchair, the table 1 is rotated and moved back, and the mounting guide is fixed to the armrest with a fixing band.
テーブル１は上面に物などを載せることができる、車椅子にテーブルを取り付けた状態で自走又は移動を行うことができる。 The table 1 can carry objects or the like on its upper surface, and can be self-propelled or moved with the table attached to a wheelchair.
車椅子の座幅は車椅子の製造会社や品種によって複数のサイズがあり、座幅が異ると肘掛幅も異なる。現状はそのサイズが３８ｃｍから４２ｃｍまであるが、２軸連結器の幅調整機能により肘掛の幅の違いにも順応したテーブルを提供することができる。 There are several sizes of wheelchair seats depending on the wheelchair manufacturer and type, and the armrest width varies with the seat width. At present, the size ranges from 38 cm to 42 cm, but the table that adapts to the width difference of the armrest can be provided by the width adjustment function of the two-axis coupler.
２軸連結器の構造は、図示しないがコの字状又はＵの字状に代えて、軸支えプレートを利用し、当該軸支えプレートに複数の軸差込口を設け、必要な軸間長さに応じてＡ軸及びＢ軸を差込み、ナットで締め付け固定した構造を採用することもできる。 The structure of the biaxial coupler is not shown in the figure, but instead of the U-shape or U-shape, a shaft support plate is used, and a plurality of shaft insertion holes are provided in the shaft support plate, and the required inter-shaft length It is also possible to adopt a structure in which the A axis and the B axis are inserted and tightened and fixed with a nut.
